Title: Improvements relating to electronic pulse selecting circuits
IPC: G01R29/027
Filed: 1954-12-08
Abstract: 757,872. Pulse width discriminating circuits. GENERAL ELECTRIC CO. Dec. 8, 1954 [Dec. 29, 1953], No. 35575/54. Class 40 (6). A pulse width discriminating circuit comprises a delay line to which the input pulses are applied and three pulse detecting devices which are coupled to definite spaced points along the line to change their state of conductivity when a pulse is applied to them and which are inter-connected so that when a particular device has its conducting status affected the effect of a pulse on the remaining devices is substantially nullified. Fig. 1 shows a pulse width discriminating and delaying circuit in which input pulses 1 from a unit 28 are applied to a delay line 2 which is terminated in its characteristic impedance 11 at the distant end. Cathode follower stages 3 and 5 are interconnected by a common cathode resistor 24 with a further stage 4 so as to function as an anti-coincidence circuit, no output pulse being obtained from the output lead 6 of the stage 4 due to a pulse at its input when either of the stages 3 or 5 has a pulse applied simultaneously at its input. Thus, as shown in Fig. 2, if it is assumed that the portion A of the delay line between points 17 and 18 and the portion B between points 18 and 19 have equal transmission times if an input pulse, Fig. 2, a, having a width greater than A+B is applied no output is obtained. If the input pulse width is less than either A or B, Fig. 2, c, an output pulse delayed, as shown, in Fig. 2, d, is obtained and if the input pulse width is greater than A but less than A+B an output pulse delayed, as shown in Fig. 2, f, is obtained. By selection of the tapping point 18 to obtain variations in the ratio A to B, different discriminating and delaying properties are obtained as shown in Fig. 2 b1-f1 and b11-f11. The output at lead 6 may be differentiated in unit 34 and one of the resulting spikes passed to load circuit 36 via clipper 35. By means of switches 37-39 the pulse from unit 10 may be compared in phase with that from points 18 or 19 in unit 40.

Title: Hydraulic forming press
IPC: B30B15/16
Filed: 1964-09-01
Abstract: 1,027,184. Stamping. CINCINNATI MILLING MACHINE CO. Sept. 1, 1964 [Dec. 18, 1963], No. 35808/64. Heading B3Q. [Also in Division B5] A hydraulic press for forming a workpiece 18 comprises a fluid pressure chamber 17 having a flexible diaphragm 16 for engaging the workpiece, a ram 18 actuated by a plurality of pistons 24a, 24b and cylinders 22, 23, a plurality of constant volume pumps (not shown) providing alternative rates of flow to the cylinders, and operating means selectively controlling the flow to the cylinders. As shown, the press has two cylinders 22, 23 arranged end-to-end, and the two pistons 24a, 24b are formed by an actuating member 24. A low pressure high volume pump and a high pressure, low volume pump are connected to the two cylinders through valves V 1 , V 2  and ports 30, 31. As the ram 18 rises, resistance to ram movement increases and one or both cylinders are connected to one or both pumps at different stages in such a way as to produce maximum ram speed at each stage. The low pressure pump is connected to the pressure line through an unloading valve which connects it to the sump when a predetermined pressure in the pressure line is exceeded. The valves are arranged so that one cylinder is connected to the pressure line before the other is disconnected, so as to prevent stopping of the ram. Two safety valves 35, 37 are opened by engagement with the upper end of cylinder 23 when the actuating member 24 reaches its upper limit of travel. The ram 18 is lowered by means of a stationary piston 45 in a cylinder 46 formed in the actuating member 24. Fluid is admitted to the cylinder 46 through a valve 49 and hollow piston-rod 47.

Abstract: 632,378. Current and voltage measurements by vacuum or low-pressure discharge apparatus. GENERAL ANILINE & FILM CORPORATION. Dec. 6, 1946, No. 36166. Convention date, Feb. 15. [Class 37] [Also in Groups XL (b) and XL (c)] An electronic measuring circuit comprising an electron multiplier tube including an anode, a cathode, and intermediate multiplier electrodes on which potentials are impressed is provided with voltage stabilizing means in circuit with the multiplier anode and the next adjacent multiplier electrode in order to maintain the potential between them substantially constant irrespective of variations in the anode current. In the arrangement shown a light source 15 is arranged to direct light upon the cathode 16 of a photomultiplier tube 20, which also includes an anode 25, an adjacent intermediate electrode 30, and eight other intermediate electrodes 17. The operating potentials applied to the cathode 16, anode 25, and intermediate electrodes 17, 30 are obtained from a voltage dividing resistor 35 having one end 21 connected to the negative terminal 22 of a constant potential source. The anode 25 is connected to the positive terminal 24 of the potentiometer 35 through the input circuit' of a pentode amplifier 40. The intermediate electrode 30 is connected directly to the terminal 24, the intermediate electrodes 17 being connected to tappings on the potentiometer 35. The anode 25 is connected to the control grid 27 of the pentode 40, a grid biassing resistor 28 being connected to the positive terminal 32 of a battery 33. The screen grid 34 also is connected to the terminal 32, and the anode 36 of the pentode 40 is connected to the positive terminal 23 of the constant potential source. The potential between the anode 25 and electrode 30 is controlled by constant potential means comprising a gaseous discharge tube 45 in series with a resistor 38, the voltage drop across the tube being about 55 volts and independent of the current through the tube. An indicating meter 50 is connected across the resistor 38 and is also supplied with a bucking current from a portion of the battery 33 through a resistor 42. The density of a sample 13 may be measured by placing it in the path of the light from the source 15, the density being a logarithmic function of the light transmitted. With the arrangement shown, the meter 50 provides direct readings of density on a uniformly graduated scale. The discharge tube 45 may be replaced by a constant potential battery. Specification 624,313 is referred to.

C., 89, Kings Avenue, New Malden, Surrey. Dec. 8, 1930, No. 36982. [Class 87 (ii).] A cellular stick of toffee or sweetmeat is made by fluting or corrugating sheets of the material, then gradually curling the edges over by passing the sheet through a stationary former, and finally severing the formed material into predetermined lengths. The corrugations may be V-shaped in cross section, or may be semicircular to project from one side only of the sheet. In the preferred construction a rod of material e is passed through plain sheeting rollers f<3>, the sheets thus formed being passed over a heated table to corrugating rolls i<1>. The corrugated strip passes through a heated former k<1> which varies in cross section as shown in Figs. 3, 4, and 5 as the strip advances, thus folding it over on itself for delivery to a conveyer m<1> leading to a flattening-roller m<3>, cutting-mechanism and a receiving-table m. Vertical side-rolls may act in conjunction with the roller m<3>. The corrugating may be performed by reciprocating plates instead of by rollers, and in some cases the strip may be perforated before being corrugated.
